For grid-scale battery energy storage systems (BESS), grounding and bonding is essential for safety and performance. The goal of grounding and bonding is to achieve customer-targeted resistance levels. These low resistance levels allow fault currents to easily discharge into the ground, protecting people, equipment and the BESS itself.
Battery Energy Storage Systems (BESS) are large-scale battery systems for storing electrical energy. BESS has become an increasingly important component to maintain stability in the electrical grid as more distributed energy resources (DER) are integrated.
